5 Claims.

My present invention relates to hair drying where heated air as the drying medium is circulated or impinged against the hair and scalp.

With the use of present hair drying machines of which I am familiar, it requires a considerable length of time, approximately an hour, to dry the hair. This is particularly true when permanent waving or finger waving is performed, due to the fact that various ointments are utilized to set the waves, and these ointments form a coating or film on the hair through which it is dii.'- ficult to penetrate with the heated air.

An important object of the present invention, therefore, is the provision of a machine which will effect a complete penetration of all of the hair of the head with the heated air. thus resulting in greatly reducing the time required for drying. By the use of my novel machine I am enabled to completely dry a head of hair in approximately ten minutes. The advantages of this quick drying feature are numerous, and Will be readily appreciated by those skilled in the art, as well as by those being treated by said machine.

Another object of the invention is to provide means to direct the heated air first to those parts of the hair which are the wettest, that is, the sides, extreme front and back.

Another object of the invention is the provision of such a machine, so constructed and arranged that the heated air will have very little, if any, contact with the face and neck of the person under treatment.

In carrying out my invention I utilize a funnel or helmet having direct connection to a source of heated air, preferably introduced into the funnel under pressure, as by an electric fan, an electric heater being interposed in the path of the air to heat the same as it passes. 'I'he outer end of this funnel or helmet is enlarged, forming a chamber to receive a portion of the head. Within this first helmet is a second helmet, adapted also to receive a portion of the head of the person under treatment, said second funnel having an outlet at the top of the rst funnel.

Said second funnel will act as a baiiie plate upon the air being introduced into the machine and will direct said current of heated air downwardly over the front, sides and back of the hair. The outlet from the second or smaller helmet is piped to the side of the motor which serves as an inlet, and the fan which blows the air from the motor through the first funnel will act to suck the air from the second funnel or helmet. 'Ihis sucking action will operate, after the heated air has passed a slight distance below the first funnel, to draw said air upwardly. under and through the hair at the front, sides and back, eiiecting a thorough drying action of said hair, and the air will then be directed back to the blower fan and again passed through the iirst funnel so that a continuous circulation of the heated air is effected. This arrangement also requires less heating capacity on the part of the heating unit, as the air will already be preheated before contact with said heater, thus resulting in an economy of operation of this machine.

If I desired, I may position, in the second or internal helmet, a perforated baille plate, to dil rect the major portion of the air passing upwardly through said second helmet around the sides thereof, but still permitting suflicient heated air to contact with the top of the head to thoroughly dry the hair at that point.

Thus an even, quick drying of all the hair on the head is effected in an extremely short space of time, far quicker than has heretofore been considered possible, and without the usual discomfort to the person under treatment.

I believe that the machine and method of the present invention, as hereinabove disclosed are novel, and I have therefore claimed the same broadly in the present application.

The above and other features and objects of the invention, details oi construction, combinations oi parts, and advantages, will be hereinafter more fully pointed out, described and claimed.

Referring to the drawing, illustrating a preferred embodiment oi the invention,

Fig. 1 is a side elevation of my novel machine, illustrating it in use:

Fig. 2 is a top plan view of the machine;

Fig. 3 is a fragmentary medial sectional view illustrating the arrangement of the two helmets and the directions of the currents oi heated air; and

Fig. 4 is a plan view oi the perforated baille plate which may be utilized ii desired.

Referring now to the drawing for a particular description of the invention, my novel hair drier is constructed in the form of a helmet or funnel I having a reduced end 2 adapted to be connected to the sleeve 3 of a motor blower 4, this blower having a fan i constructed to blow air through the sleeve 3 and into the reduced portion 2 and thence outwardly and downwardly through the helmet I.

Fixed within the helmet I is a second helmet I.

adapted to also receive a portion of the head. as illustrated in Fig. 1. 'I'his helmet B has an outlet 1 at the top of the helmet I. in which outlet is adapted to fit the sleeve B of a exible pipe 9, :aid pipe 9 having a sleeve II on its opposite end adapted to t into a casing I2 afllxed to the side of the blower chamber 4 and over the opening usually utilized as an air inlet for said blower.

While I have illustrated a flexible pipe 9, it will be appreciated that this is for illustrative purposes only and that I am not limited thereto.

When in use the helmet I is placed over the head, as illustrated in Fig. l, in which position a portion of the head will preferably enter the helmet E, as clearly illustrated.

Thereupon the motor is started. and the Ian B will force a current of air through the sleeve I. which current of air will pass the electric heater I3. This heated current of air passes in the direction of the arrows I4 illustrated in Figs. 2 and 3.

The current of heated air will then strike the inclined walls of the internal helmet 0. and will be deflected downward around the inner walls of the helmet I. as indicated by the arrows Il.

Meanwhile, however, the fan B will be exerting a suction through the casing I2, and will thus suck the air through the pipe 8. This suction will be suiiciently strong so that the heated air will only Dass a short distance below the bottom of the helmet I before the suction will draw it upwardly. into the helmet U. as illustrated by the arrows IB, whence it will paas throush the outlet 'I and pipe I tc the casing Il as indicated by the arrows Il. and thence into the blower and back throueh the sleeve l and helmet I. Thus a continuous circulation ci the heated air is created. and as said slr is sucked upwardly into the helmet t. it will penetrate under and through the hair c! the person under treatment. thus causing a thorough permeation oi the heated air through the hair oi' said person. and e!- i'ectlng a. quick cfiicient and thcroulh drying thereof, with no resultlns discomfort to the said person.

The heated air will not pass tar enough below the bottom edges ci the helmet I to cause any discomfort to the tace or neck ci' the person under treatment.

Ii.' desired. I may position a baille plate Il provided with a plurality o! psrioraticns Il in the helmet l. this baffle plate bein! spaced from the inner walls of seid helmet by webs III, and secured to the said inner walls o! the helmet l by lugs Il in any desirable manner as by soldering. weidlns. bracing. riveting or the like.

The effect oi' this baille plate Il will be to cause the maior portie of the air under suction tc be drawn throuav the helmet l around the sdsea ci the baille plate Il. while still permitting a sun'lcient amount `ogsaici heated air under suction to pass over the-top ci the head ol the person under treatment to eil'ect a thorough drying ci' that portion of the head and heir.

The adventures, ediciency. thoroughness. and economy o! my novel machine, and ci the complete circulation oi' heated air. and the combined blowing and suction thereof, will be instantly apparent to those skilled in the art. and the merits of my novel machine have already been established and proven.

From the iol-encina' description it will be iurther seen that I have invented a new method o! drying human hair which consists in confining a strata or air surrounding` the scalp and hair ci a human head by suitable means, such as an open bottomed hood, continuously projecting heated air under pressure against the hair and scalp to cause it to thoroughly permeate the hair of a person and continuously withdrawing a 5 substantial portion of the projected air from the confined space through the hair ol said person and reheating the same and again projecting the withdrawn air against the hair and scalp by recirculation. lo

While I have necessarily described my present machine somewhat in detail, it will be appreciated that I may vary the size. shape and arrangement of parts within reasonably wide llmits without departing from the spirit of the inx5 vention.
